EJB ConverterBean应该在何处以及如何定位，以便ConverterServlet可以注入EJB？不：

"..with Java EE 6 and newer you can just put all the classes in your WAR file"

当然，我正在阅读有关此主题的Java EE 7教程。

我尝试将servlet和ConverterBean放在同一个包中。

1 个答案:

答案 0 :(得分：1)

您似乎已为名为ConverterBean的{​​{1}}定义了一个本地界面。

因此，您需要在注射点使用它：

ConverterBeanLocal

或者，您可以完全摆脱@WebServlet("/converter") public class ConverterServlet extends HttpServlet { @EJB ConverterBeanLocal converter; 界面并使代码更简单。
